After a lot of touching him, he ruins her orgasm

The other day his friend said that he would give him a handjob, sit on the chair and get ready to enjoy. this boy had always been a quick ejaculator, but the other set out to control his cumming and masturbate him with continuous stops and pulls, and subtly stroking him. but the machine forced him to jerk off so much that in the end he came, but his friend ruined his orgasm by letting him go and letting his cock reflexively release sperm.
